Over the years I started to prepare my FT847 so it would be ready to be modified for 70MHz.
During that period I came across a design from G4FUF which contains a LNA of 20dB with <1dB noise.
Recently the CT1FFU preamp was installed.
It was measurred that this preamp could go as low as -145dBm with a very low noise factor.
Did anybody try to compare both designs?
If so which one do you think is the best?
